Thousands of people have paid tribute on Facebook to an Australian teenager allegedly lured to her death by a man she met on the social networking site.The body of Nona Belomesoff was found two days after she went on a trip with the man, who told her they were going to rescue injured animals, police say. A 20-year-old man has been charged with Ms Belomesoff’s murder at a creek south of Sydney. Detectives say the case reinforces the need for vigilance when using Facebook. Ms Belomesoff, 18, is believed to have befriended Christopher James Dannevig, who police say set up a fake Facebook profile in which he claimed to work for an animal welfare group. Mr Dannevig is said to have offered Ms Belomesoff the prospect of a job with the organisation and lured her on a camping trip purportedly to look for injured animals in bushland around Campbelltown, New South Wales. “She loved animals and saw this as an opportunity to follow her dream,” her brother Gary said. “Nona said if she didn’t go she would lose her job and this job was her dream,” he said. “So she just went and that was the last time we saw her.” When Ms Belomesoff did not return, her family contacted the police. Officers discovered the teenager’s body on Friday night. Since then several pages and groups paying tribute to Ms Belomesoff have been set up on Facebook. Among the thousands of postings, friends have expressed their shock and grief at the killing. “Sorry you never got to live your dreams bub, you where the most beautiful girl ever and you made your parents so proud,” wrote Sellie Gibbons. Another, Joline Sam, wrote “RIP Nona, it haunts me to know that someone did this to you and i remember catching the bus with you every afternoon from school.” Detective Russell Oxford, who is leading the investigation, said the case was a reminder to young people about the dangers of trusting strangers on social networking sites. “It’s an area where predators and perverts and other people just get onto. You just don’t know who you could be talking to,” he said.
